LEWA Redesigns Plunger Pumps

Plunger pumps are known for their ability to move fluids at high pressures. LEWA plunger pumps are specifically designed to excel at this task in the oil & gas and process industries. The pump manufacturer recently announced its new generation of plunger pumps designed with split gear housings to reduce wear and maintenance costs.

The newly designed plunger pump is also characterized by its compact construction and light weight. Despite its size, the pump is incredibly powerful and accurate. The pump model can operate at drive speeds from 15 kW to 800 kW while providing flow up to 290 m3/h and pressure up to 3,500 bar. The pump offers users outstanding efficiency, low energy consumption, and a long service life.

The new pump generation permits the use of a fully balanced crankshaft which generates less noise and vibration and reduces wear. Both new quintuplex variants, the G5K 500 and G5K 800, have five plungers, translating to reduced weight of individual components and easier maintenance. The design of the pumps also allows the use to maintain and repair components without complete disassembly.

The new pump generation can be customized to fit the particular application and/or fluid, with several options for materials, different connection geometries and several options for monitoring and flushing are available for selection.
